About Lenses
VLT – Visible Light Transmission
A MEASUREMENT THAT specifies the percentage of light coming through the lens and reaching your eyes, a totally clear lens for dark conditions typically have around 90% VLT and a very dark colored lens with mirror for sunny conditions may have down to 10% VLT. Most allround lenses will be found between 30 to 60 %. In the range of POC goggles you will find alternatives for all kinds of conditions. Please note that the Visible Light Transmission for one tint can differ a bit if the lens has a single or double construction and if it has a spherical or cylindrical shape.
Colors vs. light conditions
THE COLOR SPECTRUM runs from blue to red with a lot of different shades in between. The color sensation and perception will differ between individuals and due to this the choice of lens color will to an extent be a subjective matter.
ONE BASIC RULE EXPLAINS the contrast enhancing effect by studying the color spectrum. When choosing a lens with yellow, orange, pink or red color it blocks out more of the blue end of the color spectrum. This enhances contrast, enabling you to make out shapes, objects, and bumps in the snow more clearly. These lenses work well in low light, fog and flat light, but also in moderate light. However some individuals experience good contrast by blocking the other end of the spectra as well, by using a blue tint.
IN BRIGHT LIGHT, dark tints will keep your eyes more comfortable. There is also the possibility of choosing a brighter tint but with mirror coating to block some of the light to keep your eyes comfortable. Some individuals experience green as a good lens color since this tint will dampen the color spectrum evenly, the result is that the colors will be experienced as they normally do appear.
Technology
IN ALL OUR DOUBLE LENS CONSTRUCTIONS, the outer lens is made of Polycarbonate, which has the best anti scratch treatment available, with proven test results. All models with the Polycarbonate lens are 100% (99,9%) UV blocking and they also provide good penetration resistance.
WHEN TALKING ABOUT ANTI FOG PROPERTIES, the main factors are the material used in the lens, the quality of the anti fog coating and single vs double lens construction. All our inner lenses are made of the highest quality Cellulose Propionate and come with an anti fog treatment which outperforms the requirements of the Ski goggle standards EN 174. Hence, all our goggles with double
lens construction have an outstanding performance when it comes to anti fog properties.
IN OUR ONLY SINGLE LENS construction, Iris Comp, the lens is made in Cellulose Propionate with a anti fog coating to enable the best anti fog properties possible in a single lens. The single lens is used to minimize the optical distortion and in this case the lens will not have the same high degree of protection against scratches as a Polycarbonate lens.
THIS MEANS THAT OUR double lens goggles are the right choice unless you are competitive racer who wants to use the Iris Comp single lens to absolutely minimize all the effects of optical distortion.
